The Laboratory of Immunomonitoring in Oncology (LIO), created at the end of 2014, is a translational research unit. The main objective of the laboratory is to identify blood or tumor biomarkers that can predict the response or resistance to anti-tumor immunotherapies, as well as the emergence of some immunological adverse effects that may be linked to these treatments. Another objective is to understand the mechanisms of action of anti-tumor immunotherapies.
